From IRONMAN TriClub Program, Americas:
Hello Vulcan Triathletes,
Effective today, your club will now be in Division IV and will remain there throughout the 2018 season. We will reassess your number of affiliated athletes in December.
Divisions are based on total affiliated raced athletes from the prior year (2017). If a member has yet raced an IRONMAN event and plans on completing an IM event in the future, please encourage them to affiliate with you club – it will not affect your division size.
Division I: Over 200 athletes
Division II: 126 - 199 athletes
Division III: 76 - 125 athletes
Division IV: 26 - 75 athletes
Division V: Under 25 athletes
